Specification of Letters Patent.

Patented Jan. 2 6, 1909.

Application filed November 30, 1907. Serial No. 404,563.

To all whom it may concern:

Be it known that I, HORACE M. TALLMAN, a citizen of the United States,residing at Shelbyville, in the county of Shelby and State of Illinois,have invented certain new and useful Improvements in Baling-Presses, ofwhich the following is a specification, reference being had therein tothe accompanyin drawing.

y present invention relates to improve ments in baling resses, and oneof the objects is the provision of a means whereby I obtain a maximumstroke of the plunger in order to obtain a lar e feed opening with aminimum stroke of the trip-lever, the said mechanism being preferablycam sha ed so that as it moves the pitman forwar very rapidly, the draftbeing very close to the center or the start, the pifman travels fartherand comes up to the heavy pressure, and the cam b this time havingpassed over the center efore coming to the heaviest pressure at thisoint, ains 1n leverage and decreases the dra t. I ave found by exerience that the cam must be what I term oblong shaped instead of round,as it is the only means whereby I can secure enough movement for a threebeat baling press, and further by this peculiar shaped cam I am able togain very much in the quick movement of the pitman when there ispractically little draft, and at the same time get three beats as easyas it is possible to secure two with a plain round cam or wheel.

Another object of my invention is the provision of means for operatingthe cam and pitman and to also operate a self-feeding mechanism at aperiod when the plunger is in its farthest forward position, when agreater amount of the material to be baled is fed within the balingchamber.

Another object of In T invention is the provision of means where y therelative length of the baling press may be shortened duringtransportation, or in other words, my baling press is telescoping.

In the accompanyin drawings :Figure 1 is a side elevation of thecomplete press telescoped and ready for transportation. Fig. 2 is asimilar view of the ress read for o eration. Fig. 3 is a to flan view tereo Fig. 4 is an enlarge broken side elevation of the press near thebaling chamber showin the operation. of the cam, the extreme orwardposition thereof being shown in dotted lines. Fig. 5 is an enlarged topplan view of the forward end showing the self feed mechanism inoperating position. Fi 6 is an enlarged detail view of the sel feedmechanism. Fig. 7 is a front elevation of the forward end of the balingpress. Figs. 8 and 9 are views to clearly show the feeding mechanism.Fig. 10 is a detail view of the spring controlled side of the selffeedmounted upon its side of the baling chamber.

Referring to the drawin s:-The numeral 1 designates the hop or w ichleads to the baling chamber 2. n the forward inclined wall 3 of thehopper I provide the slots 4 throu h which project the curved arms 5, ofthe se -feed device, these arms are secured to the rock-shaft 6, whichis journaled in bearin s 7, upon the frame 8. Upon one end of this shaftis a crank 9 in which is pivoted a link 10, which has acting thereon aspring 11, which normally holds the self-feeding arms above the hop er(Fig. 10). Upon the other end of the roc -shaft, I mount the cam arm 12,which is provided with the groove or slot 13, in which is connected theend of the chain 14, which passes downwardly and around the pulley 15,journaled upon the exterior lower side of the baling chamber. Themechanism for operating this chain will be explained hereafter.

Slidingly mounted Within the baling chamber is the plunger 4(),whichconsists of the two side walls 41, which taper from the upper edge tothe lower rear edge and form the proections 42, provided with a slot 43thereetween. Upon the upper face of this plunger is provided a plate 44,having the two terminals 45, which provide a slot 46 for the passageofthe pitman or arm 47, which is pivotally connected at 48, within theplunger and has its other end pivotally connected at 49, to the reducedend of the yoke 50, the extended ends 51, being pivoted upon the shaft52, between the standards 53 of the frame.

Upon the pivot 49, I short link 54, the same being in the slotte end 47of the pitman. To the free end 54 of this link is connected a chain 55,which passes down and is connected by means of a pin 56 in the groove57, of the oblong sha ed cam 58, the pin 56 being at a point wit in butopposite the knuckle 59 of the cam, which is further provided with themount the swinging1 straight portion 60, which is approximately at rightangles with the short end 61 of the earn, the straight portion 60 furtherterminating in the rounded curved portion 62, for the reception ofthe remainder of the chain which passes forward and is connected to thecurved bar or link 63, pivotally connected to the trigger arm 64, whichis connected to the upper forward portion of the platform 65, which iscarried by the telescoping frame 66.

Pivoted to the forward end of the frame 66 by means of the verticalshaft 67 is the hollow rectangular frame 68 carrying the front axles andwheels and providing a space for the rotation of the three fingers ortrip lever 69. Each arm is provided upon its end with the downwardlyrojecting roller studs 70, by means of whicff the self feed and pressingmechanism are operated. To the upper extreme end of the vertical shaftis mounted or secured a cross bar 71 to which is connected the usualsweep 72. As the sweep rotates the shaft, the trip lever is also rotatedso that one of its studs 70 will engage the notched end 73 of the tripblock 74, which is pivoted to one end of the double lever 75, which ispivoted at 76 to the bracing-plate 77, and the frame 66, its other endbeing pivotally connected to the curved link or bar 78, which isconnected to the chain 14 which 0 crates the feeding-arms. It will benote that the studs 70 are pocketed in the trirblock slightly off itscenter, the spring 79 olding the trip-block against the stud, and whilethe stud is thus approaching the feeding-arms which move into the hop erand are released just as the preceding stud 70 is engaging theshouldered portion 80 of the trigger arm of the plunger operatingmechanism; and as the sweep continues in its movements, the link andchain connected to the cam and plunger operating device is pulledforward, pulling the cams downwardly until the pitman of the plunger isin a horizontal plane, at which time the trigger is released and thespring 81 returns the plunger to the position shown in full lines, Fig.4.

The telescoping feature of my press, consists of drawing the inner endof the platform or frame 66, below the baling chamber',b means of aWindlass 66 carried by the ba ing chamber. This is attained byconnecting the strips 66 together at their ends 66*,

by means of the bar 66, the chain 66", being connected to said bar andpassing to the Windlass, which as it is wound, draws the ends .66, belowthe baling chamber and holds them elevated during transportation. Inorder to assist in holding the thus telescoped, the in 66', carrie bythe platform 66, enters t 6 opening 66, of the cross-piece 66, of theforward end of the balin chambers frame.

irom the fore connection with t platform oinig description taken in erawings, the operation of my baling press is fully understood, and it isevident that I provide a new and novel means of operating the knuckle ortog le jointed plunger, the peculiar shape of t lde oblong cam, beingproduced so that it when operated, moves the piston rod forward, thedraft chain being connected in such a position, that when the same ispulled upon the cam is moved to pull the toggle joint of the pistondownwardly, thus moving the piston toward the pressing action, thisaction straightening the toggle and giving the heaviest pressure withminimum power, the leverage being increased by the peculiar form of thecam, just as the toggle is being straightened.

Another novel feature resides in the peculiar construction of self-feedand the mechanism for operating the same, whereby its trigger ortrip-block is held pocketed against the trip lever, that is, the stud ofthe trip lever 69, enters the notch of the end 73, and is thus pocketeduntil the feeding arms have reached their lowest point within the balingchamber, the plunger at this point being in its farthest forwardposition, giving a greater space for receiving material to be baled.

What I claim as new and desire to secure by Letters Patent, is
